Cốc hình lốp xe đạp địa hình

This is a stack of mountain bike tires modeled into a cup, the tire is a Specialized ground control and the scale of the tire should be accurate. It was very demanding on my computer to make otherwise it would look better. 

It is a large file and that could be because of the way i made it but it took a while to print. 

18 hours, 0.08mm layer Extra fine setting, 0.4 nozzle, 12% infill, supports needed, ~160g. Probably could be faster but i wanted it to look good and have good definition on the knobs.
